Installation
Standard Heater Configuration
Fig. 4 shows the standard heater configuration. In
this configuration, install the heaters on the recir-
culation lines between the fluid cabinet and the
reservoirs. The feed pumps supply material to the
reservoirs through the fluid heaters. Check valves
prevent backflow into the feed lines or into the fluid
cabinet.
To heat cold material in the reservoirs, set the
heaters to the desired temperature, open the
recirculation valves and circulate the fluid using the
proportioner pump. When the fluid temperature in
the reservoirs reaches the desired level, close the
recirculation valves, open the mix manifold valves
and begin spraying. New material supplied by the
feed pumps will be heated before it enters the
reservoirs.
